"I know for one dwarf, I make a great army..."
This is Ostagar. He is currently 128 years of age. (Young for a dwarf)
He lived in the 7th age, and his father was a master smith. The armor and weapons he has were made by himself, to keep his father's tradition alive. He got his name "Broken-Helm" when he fought 8 orcs with a shattered helmet, using it like a dagger.
